FAQ - Frequently Asked Questions

Down syndrome is a set of mental and physical symptoms that result from having an extra copy of Chromosome 21. Normally, a fertilized egg has 23 pairs of chromosomes. In most people with Down syndrome, there is an extra copy of Chromosome 21 (also called trisomy 21 because there are three copies of this chromosome instead of two), which changes the body’s and brain’s normal development.

Usually, mental development and physical development are slower in people with Down syndrome than in those without the condition, it can range from mild to severe.

Mental retardation is a disability that causes limits on intellectual abilities and adaptive behaviors (conceptual, social, and practical skills people use to function in everyday lives). Most people with Down syndrome have IQs that fall in the mild to moderate range of mental retardation. They may have delayed language development and slow motor development.

Some common physical signs of Down syndrome include:

* Flat face with an upward slant to the eye, short neck, and abnormally shaped ears
* Deep crease in the palm of the hand
* White spots on the iris of the eye
* Poor muscle tone, loose ligaments
* Small hands and feet

There are a variety of other health conditions that are often seen in people who have Down syndrome, including:

Down syndrome is not a condition that can be cured. However, early intervention can help many people with Down syndrome live productive lives well into adulthood. Children with Down syndrome can often benefit from speech therapy, occupational therapy, and exercises for gross and fine motor skills. They might also be helped by special education and attention at school. Many children can integrate well into regular classes at school.

The chance of having a baby with Down syndrome increases as a woman gets older—from about 1 in 1,250 for a woman who gets pregnant at age 25, to about 1 in 100 for a woman who gets pregnant at age 40. But, most babies with Down syndrome are born to women under age 35 because more younger women have babies.

Because the chances of having a baby with Down syndrome increase with the age of the mother, many health care providers recommend that women over age 35 have prenatal testing for the condition. Testing the baby before it is born to see if he or she is likely to have Down syndrome allows parents and families to prepare for the baby’s special needs. Parents who have already have a baby with Down syndrome or who have abnormalities in their own chromosome 21 are also at higher risk for having a baby with Down syndrome. Once the baby is born, a blood test can confirm whether the baby has Down syndrome.

Researchers have established that the likelihood that a reproductive cell will contain an extra copy of chromosome 21 increases dramatically as a woman ages. Therefore, an older mother is more likely than a younger mother to have a baby with Down syndrome, but older mothers account for only about 9% of all live births each year and 25% of Down syndrome births.

While federal laws have been established to insure that all handicapped children have access to public education, children with Down syndrome can and have been included into a regular classroom.

Children with Down syndrome have been included in regular academic classrooms in schools across the country. In some instances they are integrated into specific courses, while in other situations students are fully included in the regular classroom for all subjects. The current trend in education is for full inclusion in the social and educational life of the community. Increasingly, individuals with Down syndrome graduate from high school with regular diplomas, participate in post-secondary academic and college experiences and, in some cases, receive college degrees.

Researchers have identified the genes that cause the characteristics of Down syndrome and are working to further develop mouse models, at varying stages of development, in order to enhance their basic understanding of Down syndrome and facilitate the development of effective interventions and treatment strategies.
